Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is to solve the problem that jute and kenaf fibers are degummed and lignin-removed by rough processing pretreatment process in the prior art, and the spinnability of jute and kenaf fibers is poor. , and provide a kind of pretreatment process to jute or kenaf fine processing, make jute or kenaf degumming and remove lignin processing effect, make jute or kenaf fiber texture soft, good spinnability, can make jute Or kenaf fiber is widely used in the pretreatment process of jute and kenaf for spinning and manufacturing refined hemp fiber fabrics

Embodiment 1

[0025] Present embodiment is processing object with jute (the quality of kenaf and jute is similar), before carrying out pretreatment in the present embodiment, impurity is less in described jute. The pretreatment process to described jute, comprises the following steps:

[0026] 1. stacking: the jute is placed in an airtight storage room, the ventilation pipeline of water vapor is provided in the storage room, the ventilation pipeline is opened to make the storage room full of water vapor, and Temperature is kept on 40-50 degree, and in the present embodiment, the temperature of water vapor is kept on 45 degree, and described jute is piled up 24-72 hour under above-mentioned environment, and in the present embodiment, described jute heap Put 48 hours, make fully enter the fiber inside of described jute with water vapor, make it fully soften;

[0027] 2. carding: carding the jute fiber after stacking, adopting a carding machine to card the jute fiber in the present embodiment...

Embodiment 2

[0035] The present embodiment takes jute (the quality of kenaf and jute is similar) as processing object, before carrying out pretreatment in the present embodiment, described jute is the raw hemp that contains more impurity. The pretreatment process to described jute, comprises the following steps:

[0036] 1. softening hemp: utilize the softening machine to carry out mechanical treatment to the former hemp of described jute, make impurity and part pectin in the former hemp come off;

[0037]2. stacking: the jute after softening is placed in an airtight storage room, and the storage room is filled with water vapor, and the temperature is kept at 40-50 degrees. In the present embodiment, the steam The temperature of the jute is maintained at 48 degrees, and the jute is piled up in the above-mentioned environment for 24-72 hours. In the present embodiment, the jute is piled up for 60 hours, so that water vapor can fully enter the fiber inside of the jute, make it fully soften;...

Abstract

The invention discloses a pretreatment process of jute or red ramie, comprising the following steps: (1) stacking: staking jute or red ramie for 24-72 hours in a closed environment with steam kept at the temperature of 40-50 DEG C; (2) carding: carding the stacked jute or red ramie; (3) degumming: soaking the carded jute or red ramie in a treating solution to remove pectin and lignin of the jute or red ramie; (4) pickling: soaking the degummed jute or red ramie in an acid solution; (5) bleaching: treating the jute or the red ramie which are soaked in the acid solution with a sodium hypochlorite solution to remove the pigment of the jute or red ramie; (6) water washing: washing the bleached jute or red ramie with water; and (7) oil applying: applying oil to the jute or red ramie washed with water. The pretreatment process disclosed by the invention has good treatment effects on degumming the jute or red ramie and removing the lignin, thus ensuring that the treated jute or red ramie hasgood fiber spinnability and can be widely used for spinning and manufacturing refined fibrilia fabrics.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a pretreatment process of jute or kenaf. Background technique [0002] Because hemp fiber has good moisture absorption and air permeability, low static electricity and antibacterial properties, hemp textile fabrics are more and more popular. However, because the elasticity, wrinkle resistance and wear resistance of hemp fiber are all relatively poor, and there is a tingling sensation in contact with the skin, the variety development of hemp fiber is always limited. Existing hemp textile fabrics are mainly made of flax and ramie as raw materials or by blending / interweaving such raw materials with other fibers such as cotton, wool, chemical fiber, silk, etc., but the prices of flax and ramie raw materials are relatively high. This class of hemp textiles has not been able to be more widely used. [0003] The output of jute is the second largest cellulose fiber in the world after ...
